Closing Excel using DCOM and Release()

I cannot seem to get PHP to recognise the Release function when tring to close an instance of Excel or Word opened using DCOM. This is the error message returned.. Warning: Unable to lookup release: The object invoked has disconnected from its clients. in d:\wwwroot\studentdata\word.php on line 21 The code on line 21 is just $word->Release(); The full code is:: <?php // starting word $word = new COM("word.application") or die("Unable to instanciate Word"); print "Loaded Word, version {$word->Version}\n"; //bring it to front $word->Visible = 1; //open an empty document $word->Documents->Add(); //do some weird stuff $word->Selection->TypeText("This is a test..."); $word->Documents[1]->SaveAs("Useless test.doc"); //closing word $word->Quit(); //free the object $word->Release(); $word = null; ?> Where am I going wrong?
